In many road and airport projects in the Middle East, Polymer Modified Bitumen (PMB) is being specified by consultant. Although PMBs are not new in the paving world, Suppliers and Contractors in the region are being challenged in producing these specialty bitumen, designing asphalt mixtures, and constructing pavements with PMBs. This workshop will show you what are the most common methods of design of mixtures and compare the use of the Marshall design with the newly applied Superpave Mixture Design. It will also cover the main types of polymers and other additives used in modifying bitumen, and the key considerations for selecting them; what producers of PMBs and contractors using mixtures with PMB are worried about; and how to blend materials to achieve the required PMB Grades. The workshop will also explain how certain Bitumen modifications are changing Bitumen Content and affecting performance properties of mixtures.
Held during the Middle East Petroleum & Gas Week, 29 April – 4 May 2017

DR HUSSAIN BAHIA completed his Ph.D. at Penn State University-USA in 1991. After serving as the Director of Research and Engineering Services at the Asphalt Institute, he joined the faculty at the University of Wisconsin in 1996. He is currently a full professor in the department of Civil Engineering at which he teaches and conducts research on pavement materials and design, particularly on modified asphalts, emulsions and mixtures. He has published more than 100 technical papers in refereed journals, refereed proceedings, and various conferences. He has co-authored more than 100 technical reports and working papers for project sponsors in the road paving field. Some of his notable research activities include his service as a lead researcher for the SHRP (Strategic Highway Research Program), The National Cooperative Research Program, and the Asphalt Research Consortium (ARC).
Dr Bahia is the chair of Technical Group two of the RILEM committee on asphalt mixture design and compaction, the chair of the Technical Group seven of ISAP on the characterization of bitumen and asphalt mastics, and a board member and founder of the Middle East Society of Asphalt Technologists, (MEAST). He provides consulting services for a number of companies and road agencies in the US, South America, Africa, and the Middle-East.
